The search engine site, which sometimes uses its homepage to honor prominent figures, is commemorating today’s occasion with a cool interactive, birthday surprise spinner that gives users the opportunity to play 19 of the most memorable doodle games.

Once you click on the animation, the wheel spins and lands on a game at random. Among them are Snake, Tic-Tac-Toe, Pac Man and Solitaire.

Google began its journey in 1997. The company’s founders, Larry Page and Sergey Brin, met at Stanford University, and quickly learned they both had a goal “to organize the world’s information and make it universally accessible and useful,” the site said in a statement.

Pretty soon, everyone was introduced to Google, which was named for the number “googol” (a 1 followed by 100 zeroes).

And it’s well on its way. It now serves 4.5 billion users in 160 countries speaking 123 languages worldwide.
